UNITED STATES PATENT WILLIAM TRAUTMAN, OF DONALDSON, PENNSYLVANIA.

IMPROVEMENT IN MEAT-CUTTRS.

Specification forming part of Letters Patent No. 148,006, dated February24, 1874; application filed August 4, 1873.

To all whom it Vmay concern:

Be it known that I, WILLIAM F. TRAUT- MAN, of Donaldson, in the county.of Schuylkill, State of Pennsylvania, have invented certain new anduseful ImprovementsA in Meat- Outters; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanyin g drawings, making a part of thisspecication, in which- Figure l is a perspective view of my improvedmachine, with the casing opened so as to show the interior constructionof parts. Fig. 2 is a plan view of the same with the feeding-cylinderand stationary cutter removed. Fig. 3 is a perspective View of thestationary cutter and its supporting-block; and Fig. 4 is a like viewof` one of the cleaning-knives detached.

Letters of like name and kind refer to like parts in each of thefigures. W

The design of my invention is to furnish a simple and inexpensivemachine by means of which meats may be easily and quickly divided intopieces having any desired size and it consists, principally, in thepeculiar construe tion of the feeding-cylinder, substantially as and forthe purpose hereinafter specified. It consists, further, in theconstruction and combination of the feeding-cylinder and stationarycutter, substantially as and for the purpose hereinafter shown. Itconsists, finally, in the apparatus as a whole, its several parts beingconstructed and combined to operate inthe manner and for the purposehereinafter set forth.

In the annexed drawings, A and B represent the upper and lower sections,respectively,

of the casing of my apparatus, which, in plan view, have a generalrectangular form, are hinged together so as to be capable of theseparation shown, and when closed form, i11- teriorly, a cylindricalspace, O, which, at one end, is provided with an upward-opening passage,D, and at its opposite end with a downward-extending passage, E. Withinthe cylindrical interior of the-casing is placed a cylinder, F, whichsubstantially fills the same, except at one end, where the diameter ofsaid cylinder is reduced, as shown. Suitable journals, (lr and Gr,extending. outward from the ends of said cylinder, rest withincorresponding bearings g formed in the ends of said cas ing, and enablethe former to be rotated within the latter by means of a crank, H,attached to the projecting end of one of said journals. The periphery ofthe cylinder F is provided with a series of spiral grooves, fand f,which, from the upper or crank end of said cylinder, decrease in sizeand increase in number, until at its lower end said grooves have butabout one; fourth their first dimensions. the sides of the lowersection, B, is formed a recess, I, that has in plan view a rectangularshape, and at its inner side and upper edge opens into the space C. Acutter, K, having the form shown in Fig. 3, is placed within the recessI, with its cutting-edge 7c in a line with the periphery of the cylinderF, and in rear of said cutter is placed a metal strip, L, that has suchshape as to compensate for the irregularity of the outer face of thesame, and substantially ll said recess I. A number of set screws, M andM, pass through the side of the casing B, and, bearing against the stripL, enable the same and the cutter to be pressed inward so as to causethe sharpened edge of the latter to bear against the feeding-cylinder.Two knives, N and O, secured to the sections A and B, respectively, insuch positions as to cause them to bear against the inner end of thefeed-roller F, complete the device, the operation of which is asfollows:

The cylinder F is caused to revolve, and

meat, in pieces having a suitable size, passed inward through the upperopening D, where it is caught within the grooves of said cylinder,carried against the edge of the cutter K, and by the latter is divided.A chamfer, a, within the side of the section A, immediately above thecutter, enables the meat, after division, to pass inward again, where itis again seized by the cylinder and carried forward and around until itis again brought into contact with said cutter, such operation beingcontinued until said meat has reached the rear end of the feed-cylinder,where it is removed by the knives N and O, and passes downward throughthe discharge-opening E.

It will be seen that by adjusting the cutter FFIE.

Within one of K toward or from the feed-cylinder the fine'- ness of thesubdivisionv of the meat will be correspondingly increased ordiminished.

The apparatus thus described is simple in construction, efficient inoperation, and can be furnished at a comparatively low cost.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1sl. The feeding-cylinder F, provided With spiral groovesj' f, which decrease in size and increase in number from the upper tothe lower end of said cylinder, substantially as and for the purposespecied.

2. The feeding-cylinder F f, constructed as shown, and combined with thecutter K Within the casing A B, in the manner and for the purposesubstantially as set forth.

3. The casing A B, having a cylindrical in terior, C, and provided Withthe feed and discharge openings D and E, the feed-cylinder F j',journaled Within said casing, the cutter K, strip L, set-screws M M, andcleaning-knives N and O, all constructed and combined to operate in themanner and for the purpose substantially as shown.

In testimony whereof I have hereunto set my hand this 30th day of July,1873.

'VILLIAM F. TBAUTMAN.
